This is just plain cool! Really great ingenuity and design all around. Sure, it’s pure novelty, but what a cool piece for people to play with when they come over. It reminds me a little bit of Hit Clips, a music toy from 1999, but you know, actually useful. You would insert a cartridge that looked like a mini CD case into a Hit Clips player, and it would play about a minute of the listed song. I loved mine and thought it was the coolest thing at the time.
Makes me wonder if there is a way to make this work with Apple Music/HomePod. Maybe through a combination of services like the Apple Music API and IFTTT? I might have to take a look.
